The Overseas North Narrative: Xiangliu, Marshland, and Yu
Overseas North introduces Xiangliu as Gonggong's retainer. It has nine heads, and its feeding is associated with nine mountains. Wherever it presses or reaches becomes a marshy valley. Yu kills it, but its foul blood leaves the soil unable to support grain. The text then compresses Yu's treatment of the damaged ground into the difficult phrase san ren san ju; the outcome is a terrace for several deities, north of Kunlun and east of Rouli.
The same entry closes with a portrait: Xiangliu has nine human-faced heads and a blue-green serpent body. Those facial and color details belong specifically to Overseas North. The passage supplies harm, death, and an environmental aftermath, but no weapon for Yu, no staged battle, and no required arrangement for the nine heads.
Great Wilderness North: Xiangyao and Bitter Headwaters
Great Wilderness North uses the name Xiangyao. It too calls the being Gonggong's retainer, but describes nine heads on a self-coiling serpent body and feeding across the nine lands. The places affected by Xiangyao become marshy headwaters. Their water is bitter, and animals cannot remain there. Yu blocks the flood and kills Xiangyao; its stinking blood prevents grain from growing, while the waterlogged ground remains uninhabitable. Yu blocks the site again, turns it into a pool, and the deities use it as the foundation for a terrace north of Kunlun.
This version explicitly places the killing inside Yu's flood control and adds self-coiling, bitter water, the exclusion of animals, and the pool. It does not call the heads human-faced or the body blue-green. The two passages can illuminate each other, but their distinctive details should not be presented as one verbatim account.
Xiangliu and Xiangyao: Two Names, One Commentarial Link
The base texts preserve different written names, yet share an unusual structure: a retainer of Gonggong with nine heads and a serpent body, marsh-making movement, death at Yu's hands, foul blood that ruins grain, and a location north of Kunlun. The transmitted Guo Pu commentary glosses Xiangyao as Xiangliu and explains the difference as a shift in pronunciation. Later commentators and popular retellings generally follow that identification.
Good source labeling keeps both facts visible: Overseas North says Xiangliu; Great Wilderness North says Xiangyao; transmitted commentary connects them. Both passages call the figure Gonggong's retainer. Neither makes it Gonggong's child, mount, incarnation, or second body. Its place in a flood narrative is secure, but the base texts do not confer a formal title equivalent to god of water.
Why the Difficult Phrases Are Not a Venom Attack
The broad sequence is clear, but several words are not. The term in Overseas North is commonly read as pressing, striking, or reaching. The harder phrase in Great Wilderness North is explained by the transmitted Guo Pu commentary through expelling or snorting and stopping. Both passages also contain san ren san ju. Guo's note associates it with digging or filling followed by repeated collapse, but the compact base wording does not yield a single effortless modern translation.
What the texts securely describe is damaged terrain: marshy valleys or headwaters, bitter water, foul blood, failed crops, and land unfit for animals or people. Those results should not be converted into permanent venom, acid, plague, or a precisely described spray attack. Overseas North proceeds to a divine terrace; Great Wilderness North first has a pool and then a terrace. Separating the terse text from its commentary is more honest than filling the gap with a modern monster battle.
Nine Heads and the Later Water-Monster Image
Nine heads and a serpent body are stable across both accounts. Overseas North adds human faces and a blue-green color, while Great Wilderness North supplies the coiling posture. The number is explicit; a fan, three-tier cluster, nine long necks, or any other anatomical layout remains an artistic solution. The Xiangliu image preserved in the early-eighteenth-century Imperial Encyclopedia shows one later visualization, not an eyewitness portrait from the era of the base text.
Modern fiction and games often give Xiangliu venom, regeneration, water magic, or the rank of water god or demon king. Those traits may define a new adaptation, but their source is the adaptation itself. Similarity to the Greek Hydra is likewise morphological rather than proof of textual descent. In the Shanhai Jing, the most precise brief identity is Gonggong's retainer, and the narrative emphasis falls on land that remains damaged even after Yu kills the creature.
